He seized his hat and rushed downstairs. But here another difficulty beset him. It was easy enough to take the ordinary road to the convent, but would SHE follow that public one in what must be a surreptitious escape? And might she not have eluded the procession that morning, and even now be concealed somewhere, waiting for the darkness to make her visit. He concluded to patrol the block next to the hotel, yet near enough to intercept her before she reached it, until the hour came. The time passed slowly. He loitered before shop windows, or entered and made purchases, with his eye on the street. The figure of a pretty girl,--and there were many,--the fluttering ribbons on a distant hat, or the flashing of a cambric skirt around the corner sent a nervous thrill through him. The reflection of his grave, abstracted face against a shop window, or the announcement of the workings of his own mine on a bulletin board, in its incongruity with his present occupation, gave him an hysterical impulse to laugh. The shadows were already gathering, when he saw a slender, graceful figure disappear in the confectioner's shop on the block below. In his elaborate precautions, he had overlooked that common trysting spot. He hurried thither, and entered. The object of his search was not there, and he was compelled to make a shamefaced, awkward survey of the tables in an inner refreshment saloon to satisfy himself. Any one of the pretty girls seated there might have been the one who had just entered, but none was the one he sought. He hurried into the street again,--he had wasted a precious moment,--and resumed his watch. The sun had sunk, the Angelus had rung out of a chapel belfry, and shadows were darkening the vista of the Alameda. She had not come. Perhaps she had thought better of it; perhaps she had been prevented; perhaps the whole appointment had been only a trick of some day-scholars, who were laughing at him behind some window. In proportion as he became convinced that she was not coming, he was conscious of a keen despair growing in his heart, and a sickening remorse that he had ever thought of preventing her. And when he at last reluctantly reentered the hotel, he was as miserable over the conviction that she was not coming as he had been at her expected arrival. The porter met him hurriedly in the hall. "Sister Seraphina of the Sacred Heart has been here, in a hurry to see you on a matter of importance," he said, eyeing Key somewhat curiously. "She would not wait in the public parlor, as she said her business was confidential, so I have put her in a private sitting-room on your floor."
